power button not working PC turns on without even pressing the power button

[17030644]

I built a pc two days ago and as soon as I plug the computer to the AC outlet, the PC powers on

 

my guess is that the power button is shorted (even though I was very careful when soldering the PWR_BTN and GND wires to the button, indeed I used insulating tape between the solder joints)

 

But perhaps there's a function in the OS that does that?

 

Specs: generic case + PWR button that is also generic and seems to pertain to a different case (color scheme is different)

I barely changed windows settings, only to prevent discord from launching along with windows

A defective PSU can surge a power on signal. Disconnect your power button from your motherboard and see if the problem persists.

Most likely the BIOS is set to power on when AC is connected, option is usually called "restore on AC power loss" or such and can be either set to off, on, or "whatever state it was in upon loss".

I'll see if I can find that option in the bios, thank you
